Hey there!
One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us . If we simplify this, we get
.
Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us . If we simplify this, we get
.
One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us .
Have a terrificly amazing day! :D
